Gold Rhinstone necklace and 14k gold buying post gemstone faux pearl earrings

Product Name: Gold Rhinstone necklace and 14k gold buying post gemstone faux pearl earrings
A rare unique necklace vintage necklace. The pendent has a pink gem stone it doesn't look like a rhinestone maybe pink tourmaline. Im not sure I'm gonna say faux Stones/pearl as I'm unsure. The Necklace is most likely 9-10kt gold it was tested 3 times (pics of the last test) at 14k It dissolved mostly with a slight amount staying behind so good sign for 10kt but it's not 14k and at 10kt Acid no dissolve. So the chain tested as possible 10kt pendent maybe low kt or plated. I am selling it at gold toned /plate price since I'm not positive it's gold. The test weren't as clear as I like to say 4 sure so you might get lucky and it's 10kt for plate $ The weight is with pendent attached. The chain and pendent are in good vintage condition only issue w/pendent is on the back layer is off (pic above)The earrings are new vintage on card still there 14kt gold filled post in good vintage condition but looks buying like 1 of backs was replaced brand is rio. Review all Pics 4 details/condition/size.
